Technical Field

[0001] This utility model relates to the field of material feeding and weighing technology, and in particular to an automatic weighing device with transfer feeding. Background Technology

[0002] In the fields of explosives, chemicals, and other industries, accurate metering and automated conveying of powder raw materials are crucial for ensuring product quality and production safety. Current technologies employ manual metering methods, which suffer from low efficiency, inconsistent results, and insufficient safety. Furthermore, existing equipment often lacks efficient waste disposal mechanisms, making it difficult to meet the demands of continuous production. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic weighing device with transfer feeding that is compact in structure, accurate in measurement, and has waste classification function, so as to realize the closed transfer and accurate delivery of materials.

[0004] This utility model is achieved through the following solution:

[0005] An automatic weighing device with transfer feeding includes a frame, on which a raw material bin and a weighing sensor are mounted; a feeder is connected to the outlet of the raw material bin, and the outlet end of the feeder is located above the weighing sensor; a receiving cup for receiving material is mounted on the weighing sensor; a transfer device for transferring the receiving cup is also mounted on the frame; a feeder is located below the end of the transfer path of the transfer device; the receiving cup can move between below the outlet end of the feeder and above the feeder under the drive of the transfer device.

[0006] Furthermore, the frame includes a lower box and an upper box that are internally connected; the raw material bin, feeder and weighing sensor are located in the lower box; the feeder is located in the upper box.

[0007] Furthermore, the area on the top wall of the lower box not covered by the upper box has a raw material inlet that connects to the raw material silo.

[0008] Furthermore, a waste box is also provided inside the lower chamber, located on the side of the weighing sensor away from the feeder.

[0009] Furthermore, a transition hopper is provided directly above the feed end of the feeder, and the opening area at the top of the transition hopper is larger than the cup opening area of ​​the receiving cup.

[0010] Furthermore, the transfer device includes a lifting module and a translation module; the lifting module is used to drive the receiving cup to move vertically; the translation module is used to drive the receiving cup to move horizontally.

[0011] Furthermore, the translation module is slidably installed on the lifting module, and the lifting module drives the translation module and the receiving cup to rise and fall as a whole, while the translation module drives the receiving cup to move horizontally on its own.

[0012] Furthermore, the receiving cup is connected to the translation module via a handle, and a rotating component is provided between the handle and the translation module. The rotating component drives the receiving cup to rotate and pour materials.

[0013] Furthermore, the receiving cup can selectively pour materials into the transition hopper or waste box under the drive of the rotating component.

[0014] Furthermore, the feeder is installed at a higher height than the feeder.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. The automatic transfer of the receiving cup between the feeding and conveying positions is achieved through the transfer device, realizing the automation of metering and conveying and greatly improving production efficiency;

[0017] 2. The layered rack design effectively isolates the weighing area from the output area;

[0029] Example 1:

[0030] like Figure 1 As shown, an automatic weighing device with transfer feeding is provided, including a frame 1. The frame 1 adopts a layered design, having a lower box 101 and an upper box 102 arranged sequentially from bottom to top. The bottom wall of the upper box 102 and the top wall of the lower box 101 partially overlap and communicate with each other. The area of ​​the top wall of the lower box 101 not covered by the upper box 102 is provided with a raw material inlet 103. A raw material bin 2 is connected below the raw material inlet 103 and is fixedly installed inside the lower box 101.

[0031] The lower housing 101 also houses a feeder 3, a weighing sensor 4, and a waste container 9. The feeder 3 is located directly below the raw material silo 2, with its inlet end connected to the outlet end of the raw material silo 2. The outlet end extends horizontally to form a feed pipe 301. A high-precision weighing sensor 4 is located directly below the end of the feed pipe 301 and is fixed to the bottom plate of the lower housing 101. A receiving cup 5 is mounted on the weighing surface of the weighing sensor 4 to collect material falling from the feed pipe 301. A waste container 9 is located on the side of the weighing sensor 4 furthest from the feeder 3 to receive unqualified waste material.

[0032] The receiving cup 5 is connected to the transfer device 6 via a handle 10. The transfer device 6 includes a lifting module 601 and a translation module 602. The lifting module 601 is vertically mounted on the frame 1, and its lifting path runs from the lower box 101 to the upper box 102. The translation module 602 is slidably connected to the moving part of the lifting module 601. Driven by the lifting module 601 and the translation module 602, the receiving cup 5 moves between the end of the feeding pipe 301, the weighing sensor 4, the transition hopper 8, and the waste box 9.

[0033] The handle 10 is fixed to the slider of the translation module 602. A rotating component 11 is provided between the handle 10 and the translation module 602, which can drive the handle 10 and the receiving cup 5 to rotate, so as to realize the rotation and dumping of materials into the transition hopper 8 or the waste box 9.

[0034] A feeder 7 is fixed inside the upper housing 102, and the feeder 7 is installed higher than the feeder 3. A transition hopper 8 is provided directly above the inlet end of the feeder 7. The lower end of the transition hopper is connected to the feed pipe 701 of the feeder 7. The transition hopper is located below the end of the transfer path of the translation module 602 and is used to receive materials from the receiving cup. Its opening area is larger than the cup opening area of ​​the receiving cup 5 to ensure that all materials are introduced into the transition hopper 8 when pouring. The outlet end of the feed pipe 701 extends to the outside of the frame to deliver the materials out of the frame.

[0035] The device is also equipped with a control operation module and a camera. The control panel can be used to operate components such as the feeder, feeder, transfer device, receiving cup, and weighing sensor, and the control panel can also display information about each component or the camera.

[0036] Usage: After loading the raw materials into the raw material hopper, they are fed into the receiving cup via an explosion-proof feeder and weighed. The receiving cup is placed on the explosion-proof weighing sensor. After the weighing is qualified, the transfer device will lift the hopper and pour the material into the transition hopper by lifting, shifting, and rotating. The material is then added to the corresponding mold or other target object by the shifting cylinder feeder. Unqualified materials are poured into the waste box.

[0037] Both the feeder and the delivery pipe adopt explosion-proof linear vibration, and the vibration frequency and time are adjustable, effectively preventing material blockage inside the pipe. Both the feed pipe and the delivery pipe are made of sanitary-grade seamless stainless steel, and the tail end can be quickly disassembled for easy cleaning of the inner wall. The hopper is made of stainless steel with a mirror-polished inner wall.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
